Light:

1.The speed of light is the rate at which light travels in a vacuum. It is a physical constant that is denoted by the symbol "c" and has a value of approximately 299,792,458 meters per second.

2.Light travels at a speed of approximately 299,792,458 meters per second.

3.When multiplied by 1 hour, the speed of light is approximately 1,079,252,848.8 kilometers per hour.

Pulsar:

1.Pulsars and quasars are both astronomical objects, but they are different in several ways. Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation. Quasars, on the other hand, are extremely luminous active galactic nuclei that are powered by supermassive black holes.

2.Pulsars are formed from the remnants of supernova explosions. When a massive star runs out of fuel, it undergoes a catastrophic collapse that can result in the formation of a neutron star. If this neutron star is rotating and has a strong magnetic field, it can emit beams of radiation that can be detected by telescopes on Earth.

3.It is difficult to predict what would happen if two quasars collided, as these objects are extremely far apart and are not known to interact with each other in any significant way.

Quasar Jet:

1.Quasar jets are extremely fast, with some moving at speeds close to the speed of light. However, the exact speed of these jets can vary depending on the object in question.

2.While quasar jets can approach the speed of light, they cannot exceed it, as this would violate the laws of physics.

3.Quasar jets are narrow beams of highly energetic particles that are emitted from the centers of some galaxies. They are thought to be powered by supermassive black holes that are actively accreting matter.
